Definitions

  • the invention relates to a device for opening a vehicle lock, of the type comprising an actuator or motor electric controlled by an electric control member.
  • Door, tailgate or trunk locks generally include a locking bolt locked by a locking pawl.
  • the technique is evolving towards the use of fully locks in which the accessible mechanical controls or visible from outside the vehicle are removed. That evolution results from the finding that the overlapping of orders electrical and mechanical opening does not provide sufficient security against break-in.
  • the object of the invention is to improve the locks fully electric, including man-made locks of the trade “electrically operated locks and electrical backup integrated ", allowing the opening of the vehicle even in the event of efforts exceptional and retaining the burglary security advantages fully electric locks.
  • the subject of the invention is a device for opening a vehicle lock, of the type comprising an actuator or motor electric controlled by an electric control unit, characterized by the fact that the electrical control member is shaped to mechanically control an unlocking member acting directly on the bolt of the lock, so as to unlock the bolt to allow the electric opening of the lock in the presence exceptional efforts exerted on said bolt.
  • a device comprises an actuator or electric motor, not shown, capable of move a locking pawl 1 cooperating with a bolt 2.
  • the pawl 1 has a locking spout capable of retaining it in position notches of the pawl, such as notch 2a corresponding to the closure a door, a tailgate or a vehicle trunk.
  • the actuator or motor electric not shown must overcome an effort produced in contact with the beak and notch 2a to unlock the vehicle lock.
  • Axes 1b and 2b are material axes schematized by geometric axes in dashed lines, and these material axes 1b, 2b, are integral with the support 3 for mounting the lock on the opening of the vehicle, this assembly being carried out for example by means of screws passing through the openings 4a and 4b of the support 3.
  • the actuator or electric motor not shown of the bolt 1 is controlled by an electrical control member 5, which includes a switch or an electrical means for transmitting a control signal of an opening or closing circuit and a manual control operable in two modes operation.
  • the first operating mode corresponds to a electric control of the lock in the presence of normal forces opening time of around 500 N.
  • the second operating mode corresponds to a mechanical control of an unlocking member, in presence of exceptional efforts of the order of 7,500 N, followed by a electric control of the lock.
  • the member 5 comprises a pallet 5a on which the action of the user is exerted.
  • the first mode of operation is obtained by a short actuation stroke of the electrical member of control, for example by a slight lifting of the pallet 5a
  • the second operating mode is obtained by a long stroke of the electrical control member, for example by lifting important from palette 5a.
  • the invention is not limited to lifting a pallet 5a, but also extends to different races of another organ of manual control, for example by means of a key or a member rotary.
  • the electrical control member 5 is shaped to mechanically control an unlocking member 6 acting directly on the bolt 2 of the lock, so as to unlock the bolt 2 in the presence of exceptional efforts to allow the electric opening of the lock.
  • the release member 6 comprises a sliding end 6a pushing on a conformation 7 of the bolt 2.
  • the release member 6 comprises at least two levers 6b, 6c hinged together at a point articulation 6d, whose movement is mechanically controlled.
  • the lever 6c is articulated at one of its ends on an axis integral with the support 3 and at its other end in 6d with the lever 6b; this lever 6b is articulated with a slide 6a, so as to control a sliding of the slide 6a in two sliding directions, the first is towards the bolt 2 and the second corresponds to the opposite direction, set back from the bolt 2.
  • the release member 6 operates in the manner of a knee brace whose point of articulation 6d is moved using a mechanical control, which is a control by a cable 8.
  • the cable control 8 is a control of known type with recall elastic and sheath 9, mounted between the support 3 and the electric control 5.
  • the bolt 2 has, at a point opposite the retaining notch 2a with respect to the axis 2b, a conformation 7.
  • the conformation 7 is advantageously a prismatic conformation having a plane or a push surface suitable for receiving the push from the end sliding of the slide 6a.
  • the conformation 7 came from matter in one piece with bolt 2, but could also match to a recess in the bolt, or to an attached piece attached to a recess of the bolt 2.
  • the device is shown partially in a position corresponding to the release of the bolt 2.
  • the slide 6a presses on the conformation 7 of the bolt 2 and produces an unlocking effort to overcome efforts exceptional.
  • the thrust of the slide 6a on the prism 7 corresponds at a significant effort which causes a slight pivoting of the bolt 2 around the axis 2b and a release of the contact between the spout locking of the pawl 1 and the retaining notch 2a of the bolt 2.
  • the unlocking is enough to defeat exceptional efforts, but don't not cause the unlocking and therefore the opening of the lock.
  • the cancellation of exceptional efforts allows the unlocking and electric opening of the lock by the actuator or the motor electric not shown and known per se.
  • the toggle 6 causes the slide 6a to be withdrawn when the levers 6b and 6c pass into the position shown in broken lines in Figure 2.
  • the release member 6 thus provides assistance mechanical decompression of the bolt / ratchet system during presence of exceptional efforts but does not participate in the opening door security: the burglar-proof security advantages of fully electric locks are, therefore, fully preserved by the present invention.
  • the traction exerted by the electric actuator not represented on the locking pawl 1 and symbolized by the arrow F corresponds to a moderate effort which can always be obtained by a fully electric control and actuation, as soon as the contact between bolt and pawl is released by the unlocking member 6.
  • the pivoting of the bolt 2 resulting from the action of the release 6 is sufficient to break the contact between latch and ratchet, which ensures, in all cases, the release of the pawl and allows its pulling down by an electric actuator exerting the force F to unlock and open the door, tailgate or door lock vehicle trunk.
